Anotācija Recently we have elaborated polyisoprene/high structured carbon black composites with excellent piezoresistivity effect as well as chemoresistivity effect. The task of this study is to test the thermoexfoliated graphite (TEG) as well as multiwall carbon nanotubes (with high (LMWCNT) and low (SMWCNT) aspect ratio) for their application in design of new sensitive polymer composites. TEG has been synthesized in Department of Physics of KNTSU. Polyisoprene/TEG and polyisoprene /MWCNT composites were prepared in Institute of Technical Physics of RTU. Piezoresistivity and chemoresitivity DC and AC tests of composites show promising results. Polyisoprene/TEG composite has higher sensitivity to chemicals then polyisoprene/LMWCNT. It allows to expect all the better sensitivity of polymer/single graphene composites in future.
